A niche-dependent redox rheostat regulates epithelial stem cell fate.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Intestinal stem cells (ISCs) reside in regionally variable niches that provide diverse microenvironmental cues such as tissue oxygen status, and morphogen signaling. Integration of these cues with ISC metabolism and fate remains poorly understood. Here, we show that cellular redox balance orchestrates niche factors with metabolic state to govern cell fate decisions. We demonstrate that hypoxia and Wnt signaling synergistically restrict the reactive oxygen species generating enzyme NADPH oxidase 1 (NOX1) regionally to the crypt base in the distal colon. NOX1 enables maintenance of an oxidative cell state that licenses cell cycle entry, altering the balance of asymmetric ISC self-renewal and lineage commitment. Mechanistically, cell redox state directs a self-reinforcing circuit that connects hypoxia inducible factor 1α-dependent signaling with post-translational regulation of the metabolic enzyme isocitrate dehydrogenase 1. Our studies show redox balance acts as a cellular rheostat that is central and causative for metabolic control of the ISC cell-cycle.
